Fronius Inverter Review | The Perfect Solar Inverter

Fronius inverter review article provides you authentic data from an unbiased point of view to mature your trust on Fronius brand. These are must read info because there are lots of inverter brands in the market, particularly in Australia, albeit ironically, most of them fail to keep on their promises to serve your solar system for a long time. Hence, Choosing the right brands in terms of their warranty, the number of years in this business, and an authentic background is very cardinal in the first place before purchasing the solar inverter. Most of the recent solar inverters have gone out of their old-fashioned-mediocre features and have adopted new technologies, such as smart meters for the self-consumption, built-in MPPT, snap-in convertibility, active cooling system, Superflex design, mounting system etc. One of such solar inverters is none other than, but Fronius solar inverters. We will describe why Fronius inverter is so unique due to their solar-friendly nature in our Fronius inverter’s review.

Why This Review?

Since inverter plays a pivotal role in maximizing the efficiency of the solar panels, getting the best solar inverter for your home is a must. Fronius solar inverter is the best of its kind. In the following Fronius inverter’s review, we will try to highlight every aspect of this branded inverter to make it easy for you why you ought to install one of these inverters.

A Glimpse of Solar Inverter

We all know how a solar system converts sunlight energy into its new form of usable electric energy. For this, DC electricity produced from the solar panels has to undergo a legit transformation into a grid-compatible AC electricity. Only an inverter can transform this energy into an AC electricity. AC is the widespread form of electric power that is utilised by most of the residential, commercial and industrial electrical devices and equipment.  There are mainly five types of solar inverter used for both residential and commercial properties. Cyanergy gives you a range of option to choose the perfect tier 1 inverter from the selected top-notch brands.

Fronius Solar Inverter Review

About Fronius Australia Pty Ltd

Having originated in Austria with a European heritage in 1945 by Günter Fronius, Fronius managed to establish itself as one of the most prominent companies for manufacturing welding devices, as well as battery chargers. However, Fronius was able to exert its reputation in the solar industry too. Fronius has been in the solar industry since 1992, and its first launch of the inverter for the solar system in 1995 had helped it evolve as one of the most leading and well-established inverter manufacturers in the world. Currently, there are 19 solar offices in the whole world, including the office based in Tullamarine, Victoria. This office in Melbourne is not only used for the customer service and managerial assistance but also it provides the platform for the demonstration of the products, as well as training courses. We Cyanergy, is happy to inform you that we have all the latest collections of Fronius inverter.

Latest In-Built Technology

One of the latest built-in technologies added to the Fronius is the MPPT (Multi Power Point Tracking). Most of the Fronius inverters come up with two solar inputs. If the efficiency due to Fronius inverter is 97.8%, then the addition of MPPT will increase it up to 99.9%. MPPT, as an alternative to PWM (Pulse Width Modulation), is a type of solar charge regulator linked with both solar panels and the battery to ensure that the battery gets charged properly without having an overflow of charge. It also tends to seek the ‘Sweet Spot’ or the optimum combination of voltage and current by sweeping across a series of solar panels to generate the highest efficiency simultaneously.

Why MPPT is important?

The traditional PWM used to have a direct connection starting from the panel to the battery. It seems to wait until the battery gets fully charged manually, and the voltage of the solar panels get balanced in accordance with the battery voltage. This, in turn, causes a huge loss of the efficiency of the solar panels. On the contrary, MPPT despite having shading caused by less daylight, defective modules, birds dropping or leaves, can still find the right peak of the energy point and try to use it for the sake of the better efficiency to increase it up to 30%.
The advantage of having two solar input is to connect arrays of both east and west-facing roof (if you have any) into one input, leaving another input free for the future possibility of connecting arrays of the other facing roof into that. No matter what time of the day or how inimical the weather is, the MPPT will track the MPP (Multiple PowerPoints) across the solar panels to prevent the aftermath of the shading, hence better efficiency.

Additional Values That Features Add to A Fronius Inverter

Active cooling system and noise-free: One of the most distinctive features of the Fronius solar inverter is the presence of an ‘active cooling’ system, which allows the inverters to perform better even when exposed to excess heating. Heating can disrupt the efficiency of the inverter, and at a certain point, the inverter slumps down the performance to prevent itself from getting too hot. However, excess noise produced from it can cause sound nuisance, but it’s worth it for keeping the machine away from thermal stress.

Unique snap-in design & easy to operate: Having an integrated DC isolator prevents the inverter from occupying extra space. The unique snap-in design found almost in all the recent Fronius inverters allows them to operate easily without detaching them from the wall like a car boot while installing it.
Built-in WiFi & remote control: Built-in WiFi has made it easy to be accessed from any smartphones using the solar web smartphone app. Fronius smart meter can be used to monitor the regular self-consumption, as well as the amount of electricity it generates. That’s why the price of the Fronius inverters in Australia is likely to be higher.

Longer Warranty, The Big Boon for Its User

Anything that contributes to building the whole foundation of the solar system should be taken into account for their warranty, and so is the inverter. The exciting thing is that Fronius inverter comes with a five-year warranty with an additional five-years warranty if you register at Solarweb free of charge. Should there any problem or issue arise with the warranty, the Fronius advises the customers to arrange a schedule with a qualified solar installer to have a look at the issues. If there is any, then the installer will notify the Fronius team, and they together will work to solve or replace the whole faulty inverter. Bear in mind that the customers have to pay for the installer themselves.

Different Types of Fronius Inverters

Fronius has been the backbone of manufacturing the magnificent types of welding inverters over the last 75 years, and that has intrigued them to manufacture the solar inverters. Their newly advanced snap-in inverter (snapINverter) emerged from 2012, has taken the solar inverter industry by storm in which, you can mount the inverter against the wall to open the front hood easily to function the inverter without pulling off the whole inverter. All of these robust inverters are certified with CE certification. This guarantees the customers that their inverters have met the criteria of the legislated EU requirements, and they are up to the mark in terms of their quality.
These Fronius inverters comply with the relevant Australian Standard (AS4777), which means that you can easily benefit from all the incentives and rebates that the Australian government is currently offering. You can also check out the following link to see the Clean Energy Council’s approved inverters list. That’s why they appear to be one of the first choices as the best solar inverter for home.

Still, the fantastic customer service rendered by the Fronius customer support team, along with its solving capabilities, has caught the eyes of its respective clients. Thus, Fronius received positive feedback from the customers.

Why Solar Inverter is a Crucial Part in Solar System?

The reason a solar inverter is considered to be the most crucial part is due to its proneness to damage or impairment caused by the harsh weather. Raining, snowing, humidity or extreme heat are some of the regularly faced weather-related obstacles that any inverter ranging from expensive to lower-end has to go through, and some inverters have to compromise generating thousands of watts of solar electricity for an incessant period of time in a day. As a result, the more the inverter can be taken care of, the longer it will last and benefit you in terms of generating more power.
